bit more go

hi guys im new to the forum and im just wondering if anyone has had a set of extractors made to suit a 3cyl 1l hijet. would they give the van a bit more power with a 2 inch exhaust? and any other performance modifications you guys have done to get the lil 3 cylinders goin a bit harder would b great. cheers. heres a pic of my 87 van

im from australia btw =)

Hi I think that you could play with the diff gearing but only if you never carry loads but I think a mark one or two rear axle would go in which you can get loads of different ratios and limited slips for and you would get a better choice if wheels for better rubber.
